最近做的項目中百度地圖是很重要的一個模塊，其中實現了定位、自定義Marker圖標、線路規劃、SuggestionSearch檢索、地圖截圖以及導航等功能。因為如何在自己項目中集成百度地圖在官方文檔Demo和網上已經有很多優秀并且很詳細的教程，所以這里主要記下一些本人在使用過程中出現的問題和容易出現錯誤要注意的地方。

1.地圖顯示為網格加載不出來,logcat打印錯誤
Authentication Error errorcode: 230 uid: -1 appid -1 msg: APP Scode碼校驗失敗
出現這個問題的原因一般為SHA1配置不正確
注意點:分為發布版SHA1和開發板SHA1，發布版SHA1用于keystore簽名文件打包后的程序；開發板SHA1用于直接運行debug的程序，下載官方文檔中簽名工具輸入包名就能得到
解決辦法:登錄百度地圖開放平臺修改即可
